Microscopic study on oil flow efficiency in tight formations after hydraulic fracturing

水力压裂法在加拿大已成功地应用于致密油的大批量生产。水力压裂作业后的一个关键问题是如何最大限度地提高后续石油产量。本研究将采用微观的方法来了解水力压裂处理后油流的增长情况。利用在阿尔伯塔大学设计和建造的微观模型，我们将探索在微观尺度上控制油/压裂液流动行为的机制。Fusion Technologies Inc.生产的专有压裂液。将全面评估它们在水力压裂后促进石油生产的有效性。研究结果将有助于Fusion改进其现有的压裂液配方并开发新配方。鉴于大量致密油

Hydraulic fracturing has been successfully applied to facilitate the large-volume production of tight oil in Canada. One critical issue following hydraulic fracturing operation is how to maximize the subsequent oil production. This research will adopt a microscopic approach for understanding how oil flow ensues after the hydraulic fracturing treatments. With the micromodels designed and built at the University of Alberta, we will explore the mechanisms that govern the oil/fracturing-fluid flow behavior at a micro scale. The proprietary fracturing fluids produced by Fusion Technologies Inc. will be comprehensively assessed in terms of their effectiveness in facilitating the oil production after hydraulic fracturing. The research results will help Fusion to improve their existing fracturing fluid recipes as well as develop new ones. Given that vast tight oil
